Somalian food in Haymarket
A heads up. Next to Haymarket Pizza - on the other side of Harry's Cheese - is a new pizza / middle eastern place. (Same $1.25 a slice for pizza, btw.) But it's not middle eastern, though it has shawarma and other such stuff. The left side of the menu says "Somalian." I haven't tried it. The meat is of course halal.
I've had their pizza and some of their chicken dish (don't know what it's called). I'd say they're pretty good. I don't think they're super gourmet or anything. I like it that they're reasonably priced. The pizza is also decent and very cheap. ($8.50 for the whole big pie with a topping of your choice). I had a spicy eggplant pizza that's definitely edible.
The best thing about it is the park right across the street. You could grab a takeout from there, cross the street, and there, you have one of the best outdoor dining in Boston! :)
